This screencast shows how InfoCards can be created and used at a website that allows users to authenticate using self-issued (aka Personal) InfoCards. The demo uses a pre-beta 2 version of InfoCard and an ASP.NET 2.0 web site. To see a demo with InfoCard and PHP take a look at http://www.identityblog.com/?page_id=430.
If person "A" has logged into their computer at home/office who has an InfoCard already made, and then that person leaves the room/office (without logging off first), what security measures are there to prevent person "B" from accessing a website that is InfoCard capable? I would assume that some banking sites and others would have personal information stored and easily viewed once logged into that "secure" site... that info would be open to compromise?
For me, Infocard, now CardSpace, is PKI with different names and also applied to web sites
CA = ProviderPublic/Private Key = Card
Am I wrong?
Would you mind giving us more detailed information about CardSpace compared to PKI and PGP?
